PPT-EYE AND RETINA   What is light? Where does it fit into the spectrum of electromagnetic

Why is short wavelength electromagnetic radiation dangerous to us whereas long wavelength electromagnetic radiation is considered safe Which wavelengths do we see as Light Why these wavelengths Why couldnt the shorter and longer wavelength stuff work just . Temporal filtering . – visual response slower than input signal. . 2. Spatial filtering . – local signals are combined across space to varying degrees.. . . 3. Light adaptation . – retina modifies responsiveness depending on average light level.. Almost all of our information on the heavens is derived from the light we see. We have returned samples from the Moon and a comet . Also obtained meteor samples. We have landed (with unmanned probes) on only a handful of planets and moons. Mrs. Molloy. 6. th. Grade Science. Electromagnetic Waves…. Do not need matter to transfer energy.. Made by vibrating electric charges.. Travel by transferring energy between electric and magnetic fields.. Iris. Pupil. Cornea. Lens.

We will look at the following parts:. Take notes on this page…. CORNEA . (clear lens in front of eye). transparent covering of the front of the eye. Allows for the passage of light into the eye and functions as a fixed lens.. Energy that travels as a wave through space. Wavelength –. λ – distance between corresponding points on adjacent waves. Frequency – f – waves per second. Spectrum. Breakdown of electromagnetic radiation by increasing wavelength. 1. The Electromagnetic Spectrum. Wavelength/frequency/energy. MAP TAP 2003-2004. The Electromagnetic Spectrum. 2. Teacher Page. Content: Physical Science—The Electromagnetic Spectrum. Grade Level: High School. cornea. is a very important structure in the outer avascular . fibrous tunic. It’s composed of a transparent epithelium that covers the anterior eye and helps focus light onto the retina. LASIK is a common visual corrective procedure that is performed on the cornea of the eye. Gravitational Wave Bonus). The next slides show images of the SAME region of sky, but using different types of light. The view in VISIBLE LIGHT. INFRARED. RADIO WAVES. RADIO WAVES. GAMMA RAYS. Different types of light give us different information!. . What do X­rays, light, microwaves, radio waves, and infrared have in common? . . EM Radiation. Radiation can be described as the movement of energy through space. . There are many different sources of radiation that vary by intensity. . Name the four areas which make up the cerebral cortex of the brain. Describe three ways in which scientists and doctors are able to study the function of parts of the brain. Explain why the case-study of Phineas Gage isn’t the most reliable evidence we have for providing information on brain structure and function. Light, microwave, x-ray, TV, and cell phone transmission are all kinds of . electromagnetic waves. .. Electromagnetic waves are a group of energy waves that are mostly invisible and can travel through empty space..
